براغي مقبس كوب بلاستيكية من النايلون | فولاذ سبائكي (100 / عبوة)

The hex socket drive made adjusting these set screws in a tight spot on my workbench fixture so much easier than using a standard Allen key. The nylon pellet tip grips the shaft firmly without marring the surface, exactly what I needed.

Installed these in a couple of jigs and the nylon pellet really does hold tight without marring the shafts. The hex socket made it easy to get them snug in tight spots.

These tiny set screws have a nice sharp cup point that bites in really well. The nylon pellet is a clever touch for locking things down without damaging the surface. Worked perfectly for a positioning jig I was building.
